Hom kev cog ntoo hauv tsev tsis zoo rau peb. Nws yog tsuas yog siv los ntawm kev cog paj - kev sim thiab cov neeg ua paj "paub ntau yam". Cov kev teeb tsa no tsis tau nrov npe vim yog qhov zoo nkauj ntawm cov ntaub ntawv sab nraud thiab qhov nyuaj ntawm cov khoom siv. Hydroponics feem ntau siv rau hauv kev lag luam rau cov nroj tsuag loj hlob. Thiab cov paj zoo nkauj nyiam siv cov av sib xyaw nrog ntau yam. Tab sis yog nws yeej nyuaj ntawd? Yuav ua li cas siv hydroponics hauv tsev?
Hydroponics yog ib txoj hauv kev uas cov nroj tsuag tuaj yeem loj hlob yam tsis muaj kev siv av, siv tsuas yog tshwj xeeb kev daws teeb meem ntawm cov dej raws li dej. Hloov chaw ntawm lub ntiaj teb zoo tib yam, lawv siv cov txiv maj phaub ua kom zoo dua, perlite lossis me me nthuav av nplaum - lawv zoo tshaj rau cov nroj tsuag hauv tsev. Xws li cov looj tau muaj dej zoo thiab huab cua permeability, tsis txhob cuam tshuam nrog cov kua aqueous tshwj xeeb. Kev siv tsawg dua yog polyethylene, quartz, granite lossis iav hauv granules.
Cia peb sim ua kom paub yam tsis muaj teeb meem kev sau duab yuav ua li cas thov hydroponics tom tsev thiab yuav ua li cas thiaj ua rau cov cuab yeej no koj tus kheej.
Txhawm rau tsim "hydroponic device" koj yuav xav tau ob lub thawv ntim, piv txwv li, ob lub paj paj, ntawm qhov ntau thiab tsawg. Lub lauj kaub me me yog npaj ncaj qha rau cog ntoo. Hauv cov lauj kaub no koj yuav tsum ua kom muaj cov lej me me ntawm lub qhov me me, koj tuaj yeem siv ib txheej nyias nyias thiab kub ntawm cov ntsia hlau. Peb sau lub paj no muaj peev xwm nrog kev npaj substrate thiab cog ib tsob ntoo hauv nws.
Lub taub loj dua yuav tsum tau ua ntawm cov khoom ntom ntom uas tsis pub cov dej thiab lub teeb hla dhau. Nyob rau hauv lub lauj kaub loj, koj yuav tsum hliv cov kua aqueous tshwj xeeb nrog ntxiv ntawm cov hydroponic chiv lossis cov ntsuas kev loj hlob. Cov kua dej no yuav muab cov khoom noj tsim nyog rau cov hauv paus hniav. Cov khoom ntxiv no tau muag hauv cov khoom loj hauv txhua lub khw muag khoom ntsig txog kev cog ntoo.
Lub thawv me dua yuav tsum muab tso rau hauv lub thawv loj dua. Nws yog qhov tseem ceeb heev uas cov hauv paus hniav tsis tau muab xaus rau kev daws teeb meem, tab sis tsuas yog hauv ob feem peb ntawm nws cov khoom (kwv yees li 2 centimeters). Koj yuav tsum tau saib xyuas tas li theem ntawm cov tshuaj. Hauv paus txheej txheem ntawm cov nroj tsuag yuav tsum tsis txhob qhuav tawm. Nruab nrab ntawm lub qab ntawm ob lub thawv yuav tsum muaj kev ncua deb kwv yees li 5 centimeters.
Hauv txoj ntsiab cai, kev tsim cov khoom siv hydroponic xaus ntawm no. Nyob rau hauv dav dav, tsis muaj dab tsi nyuab nyob rau hauv no. Txhua tus neeg uas txiav txim siab sim ua cov qauv no ntawm kev cog ntoo hauv tsev yuav tuaj yeem nyab xeeb rau kev lag luam.
Hydroponics yog qhov zoo rau kev cog tej nroj tsuag: rau cov zaub qoob loo, cov txiv ntoo, cov tshuaj ntsuab thiab cov paj hauv tsev. Siv hydroponics nyob rau hauv chav tsev dog dig, koj tuaj yeem tau sau qoob loo ntawm radishes, cucumbers, txiv lws suav, kua txob, txiv pos nphuab thiab cov mint uas muaj ntxhiab. Thaum loj hlob ntawm cov nroj tsuag sab hauv tsev, tshwj xeeb tshaj yog yuav tsum tau saib xyuas tsuas yog siv rau cov uas muaj cov hauv paus hniav tuaj yeem ua kom yooj yim.
